I'm using redis pub/sub to receive keyspace notifications for the expired keys. The solution works fine with the redis instance that doesn't have cluster mode enabled, but when switching to a cluster deployment it sometimes drops the connection and the subscriber won't reconnect.
I'm using Elasticache 7.0.7 Cluster Deployment with 2 shards & 2 nodes per shard.
The output of debug logging for the subscriber is the following

The pub/sub subscriber is in a fargate task inside the same VPC as the redis instance.
I've also checked the maintenance of elasticache if it caused this, but I didn't find anything that happened. The instance was working normally as always.
If this issue can't be solved how can I retry the whole subscription manually if this ever occurs?
